'UNITED STATES DAVID OROMWELL, OF ST. LOUIS, MISSOURI.

IMPROVEMENT IN REFRIGERATORS.

Specification forming part of Letters Patent No. 119,508, dated October 3, 1871.

.To all lwhom it may concern:

Be it known that I, DAVID GROMWELL, of St. Louis, in the county of St. Louis and State of Missouri, have made a certain new and useful Improved Refrigerator; and I do hereby declare that the following is a full and true description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

This invention consists in a new arrangement of ice-chamber in combination with provisionchambers, the ice-chamber being constructed to form an L-shaped ice receptacle round the top and at one side of said provision-chambers; and also in certain detail construction of parts, all of which will now more fully appear.

To enable those herein skilled to make and use my said improvements, I will now more fully describe the same, referring to- Figure l as a top-sectional plan at line x y Fig. 2 as a longitudinal sectional elevation at line :v1 y1; Fig. 3 as a transverse sectional elevation at line m2 y2.

The chest or box A of the refrigerator is constructed as usual, having hinged door B on top, front doors B1 B2. Also, said box and doors are packed or fitted as usual, with suitable non-conducting material. Each of the doors B B1 B2, however, have thin closing edges iitted with rubber strips, b, to form air-tight iit. The interior of the box A will be lined with galvanized metal. The interior chamber is divided by top ice-chambers O, the lower chamber being further divided by a partition, c, to form provision-chambers G1 G2. The division between ice-chamber C and the said provision-chambers being made by an L- shaped ice-chamber or receptacles, d d', round the back and side of an elevated ice-iioor or support, D, in mannerillustrated in the figures. Said icefloor D (forming also main top of chambers G1 C2) has its top and sides constructed slanting backward, to conduct the water back to L-shaped chamber. (See Fig. 3.) It will be noticed that on top said ice-floor D the ice can be stored in large cakes and thus kept to last a longer time; also, the L-shaped chamber is fitted with ice.

Thus, by supporting the ice on top and arranging the L-shaped ice-chamber round the back and side of the provision-chambers G1 O2,.the same receive all the benefits of the refrigeration process in the ice-chamber proper. Furthermore, by

means of the side ice-chamber d aperfect freeze77 v can be obtained in its Acontiguous provision -chamber O1, and a chill 7 in the provision-chamber C2 to accommodate the kinds of provisions to be kept. To strengthen the ice-flooring D the same has attached or soldered stays d2, and these are further utilized by hooks cl3. The interior of such provision-ch amber is provided with shelvings as ordinarily. To the back of the ice-chamber is a cooler, E, for ice-water. It has the hinged door o. The water-pipe F communicates with the bottom of the cooler, its stop-cock j' being in front. The exhaust or waste-pipe F connects with the L-shaped ice-chamber, passing out at the bottom. The arrangement of each of said pipes F F is made to pass through the provision-chamber C2 to prevent freezing of the pipes, and as clearly shown in Fig. 3.

Having thus fully described my said improvements, what I claim is- In combination with the provision-ch ambers Gl C2, the ice-chamber C, its slanting ice-support D, provided with stays d2 d3, and the L-shaped ice-receptacle d d1, all constructed and arranged substantially as and for the purposes described.

In testimony of said invention I have hereunto set my hand.
